- Summary
- CVE-2026-74625 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
netfilter: bridge: release template ct on non-IP path
A bridge nftables ct zone set rule can attach a conntrack template to an skb before nfctbridgepre() sees it. For non-IPv4 and non-IPv6 EtherTypes, nfctbridgepre() currently overwrites skb->nfct with IPCT_UNTRACKED without releasing the existing template reference.
That makes the per-cpu template, and any temporary templates allocated for concurrent use, unreachable and leaks memory until the host runs out of slab.
Reset the skb conntrack state before marking the frame untracked so the existing template reference is dropped on the non-IP path.
